What phase of operations involves setting the stage for follow-on UTCs?

The phase of operations that involves setting the stage for follow-on UTCs is accurately identified as the phase where forces establish the necessary conditions that allow subsequent units to effectively carry out their missions. Opening the base entails initial actions such as securing the area, establishing communication, and preparing infrastructure, all of which are critical to ensure that later UTCs can seamlessly move in and continue operations.

This phase is foundational, as it ensures that all logistical and operational frameworks are in place, allowing for a smoother transition as additional forces arrive. It is the initial step that prioritizes readiness and support for follow-on units, creating an effective environment for them to operate or expand their mission capabilities.
